摘要： The present disclosure is drawn to inertial pumps. An inertial pump can include a microfluidic channel, a fluid actuator located in the microfluidic channel, and a check valve located in the microfluidic channel. The check valve can include a moveable valve clement, a narrowed channel segment located upstream of the moveable valve element, and a blocking element formed in the microfluidic channel downstream of the moveable valve element. The narrowed channel segment can have a width less than a width of the moveable valve element so that the moveable valve element can block fluid flow through the check valve when the moveable valve element is positioned in the narrowed channel segment. The blocking element can be configured such that the blocking element constrains the moveable valve element within the check valve while also allowing fluid flow when the moveable valve element is positioned against the blocking element.

摘要： In an example implementation, a method of controlling a microfluidic valve includes activating a first inertial pump at a first frequency, and a second inertial pump at a second frequency to create a first fluid flow pattern within a microfluidic valve. The method also includes adjusting at least one of the first frequency and the second frequency to change the first fluid flow pattern to a second fluid flow pattern.

摘要： A vibrational fluid mover assembly having an active damping mechanism is disclosed. The vibrational fluid mover assembly includes a vibrational fluid mover having a first plate, a second plate spaced apart from the first plate, a spacer element having an orifice formed therein and being positioned between the first and second plates to maintain the first and second plates in a spaced apart relationship, and an actuator element coupled to at least one of the first and second plates to selectively cause deflection thereof such that a fluid flow is generated and projected out from the orifice. The vibrational fluid mover assembly also includes an absorber system connected to the vibrational fluid mover and providing active damping to the vibrational fluid mover, with the absorber system having suspension tabs coupled to the vibrational fluid mover and spring components configured to mount the vibrational fluid mover in a suspended arrangement.

摘要： A piezoelectric blower includes an outer casing and a blower main body. The outer casing houses the blower main body. The blower main body includes a top plate, side plate, first vibrating plate, piezoelectric element, intermediate plate, second vibrating plate, side plate, and bottom plate and has a structure in which they are laminated in sequence. The top plate, side plate, and first vibrating plate define a columnar first blower space. The second vibrating plate, side plate, bottom plate define a columnar second blower space. The distance from a neutral plane of the piezoelectric element in the thickness direction to a surface of the second vibrating plate, the surface being near the piezoelectric element, is longer than the distance from the neutral plane to a surface of the first vibrating plate, the surface being near the piezoelectric element.
